CORPORATION OF DELAWARE STOVE Application filed J'une 14 This inventionrelates to heating stoves of the type in which a stove is mounted in asupair is admitted to be heated by the stove and from which the heatedair passes to the outside of the easing.

An object of the invention is to provide improved means for controllingthe c rculation of the air into and from the casing in which the stoveproper is enclosed. Another object of the invention is to provide meanswithin the casing for damping or baffling the ascent of the heated airwithin the casing so as to regulate and control the circulation.

Another object of the invention 18 to provide a casing for enclosing astove proper and provided with louvres in the walls, in combination withdamping or baffling devices movable to positions between the stoveproper and the walls of the casing containing the lonvi'es so as toprevent the rapid ascent of air between the stove proper and the casingwalls having the 'louvres, thus retarding and deflecting the heated airthrough the louvres and closer to the floor of the room containing thestove.

Other objects will appear from the f0llowing description, referencebeing made to the drawing in which n a Fig. 1 is a vertical sectionalview of a stove embodying the present invention andlooking toward theinside of the rear wall of the casing.

Fig. 2 is a view looking toward one of the lateral side walls of thecasing showing the arrangement of one of the louvres- Fig. 3 is aperspective view of one of the guard devices for protecting the casingwalls from the intense heat of the enclosed stove.

Fig. 4 is an enlarged sectional view, on the line 4l4 of Fig. 2, showingthe louvre construction.

The front wall and doors of the casing are omitted from the drawing, asillustration of 1923. Serial'No. 285,245.

shown) and the top wall 45 form the exposed part of. the casing which issupported by legs 5. The upper portion of the rear wall 1 has an opening6 formed through it to accommodate a stove pipe extending from the stove7 enclosed within the casing. The opening 6 is surrounded by an inwardlyextending marginal flange 8 which reinforces and strengthens theadjacent wall structure. The upper end wall 4 is provided with a numberof bosses or thickened portions 9 which seat upon flanges 10 formed byinwardly extended por-' tions of the casing walls. Screws 11 passthrough the wall flanges 10 and engage within the bosses 9, thus rigidlysecuring the top wall in connection with the vertical casing walls.

Each of the lateral side walls 2 is protected from the intense heat ofthe stove 7 by a liner device. The liner device for each of the walls 2comprises a metallic plate 12 having a sheet 13 of heat insulatingmaterial, such as asbestos, attached to its outer side. These liners aresupported from the flanges 10 by hooks 14L attached to the liners andengaging the flanges and are held in spaced relationship from theadjacent walls 2 by vertical channel members 15 and angular arms 16. Thechannel members 15 are attached to the liners and have their flangesextending outwardly toward the walls 2 with which said flanges maycontact. plates 12 and are of angular formation so that they engage withthe walls 2.

Each of the walls 2 is provided with a louvre window which may be madeby splitting said walls horizontally and downwardly at the ends of thehorizontal splits and bending inwardly the parts 17 defined by thesplits and forming louvre boards or slats. While these louvre boards orslats 17 are shown as formed integral with the walls 2 it is obviousthat they may be arranged otherwise, if desired.

The lower edges of the liners for the lateral side walls 2 terminateapproximately as shown in the plane of the upper ends of the louvres,though this arrangement may be varied, if desired, without departurefrom the principle of the invention.

The arms 16 are attached to the For the rear casing wall 1,1 provide asimilar liner similarly supported and provided at its upper end withnotch 18 to receive the stove pipe or flue. The liner for the rear wallextends downwardly to a considerable cistance below the lower ends ofthe liners for the lateral side v-ralls and terminates above the airinlet openings 19.

My ini-ention comprises a damper or baffle for controlling ancregulating the ascent of tee enterin the casing through the open lowerend frame and through the louvres and through the holes 19. Thesedampers or battles ma oe supported as desired and, as shown, saiddampers or baiiies comprise a pair of plates 20 mounted on horizontalpivots in connection with the sides of the stove 7 toward the louvrewalls 2. A feature is that tie plates 20 are supported by too stoveproper and not by the casing. From one of these dampers or baffles 20 achain 22 eX- tends over supports 23 and thence outwardly through opening12% in the top wall a for manual engagement and operation. From theother damper or baffle 2-0 chain 25 e tends to sliding connection 28with the chain 22 so that by drawing the drain 22 taut both dampers orhaflles 20 will be moved to approximately horizontal positions in whichtheir outer edges areclose to the louvre wall 2 and near the upper endsof the louvre. This prevents too rapid circulation of the air throughthe casing by retarding and baiiiing cie air entering the casing, so eair is retained in the casing for a on and becomes heated to a ate:degree. However, the heated air is permitted to rise at the front andrear of the stove 7 and to pass out through the perforated top wall l.

From the foregoing it will be seen that while the air may freely enterthe casing it does not freely pass to the top of the casing at thelateral sides of the stove proper. A part of the heated air is deflectedoutwardly and downwardly because of the proximity of the louvre to thedampers 20; and the dampers or bafiles 2O retard ascend of the air untilthe air is properly heated so that a room may be more quickly andsatisfactorily heated than if cold air were permitted to circulatethrough the stove casin The construction and arrangement of my improvedstove may be varied within equivalent limits and in other respects thanthose specially mentioned. I contemplate such variations as may be founddesirable or expedient and do not restrict myself unessentially in anyrespect.
